What type of memory do most solid-state drives utilize?

• A. DRAM
• B. NAND flash memory
• C. EPROM
• D. MRAM

Answer: (B)

Solid-state drives store data in non-volatile flash memory designed for high density and cost efficiency. That type is NAND flash memory, which preserves data without power and can be scaled to hold large amounts of information. DRAM, while often used as a fast cache inside many SSDs, is volatile and not the primary storage medium. EPROM is an older non-volatile memory technology with limited rewrite capability and isn’t used for bulk storage in modern drives. MRAM is a newer non-volatile technology still not adopted as the main storage medium in consumer SSDs. So the main storage material in most SSDs is NAND flash memory.
